Getting Argument Cannot Be Null Parameter name: assemblyName XAML

I just cannot figure this out. I am trying to use a converter for a StaticResource call. On app startup I get the error Argument Cannot Be Null Parameter name: assemblyName XAML. Here is what I have.

Converter Class:

using System;
using System.Globalization;
using System.IO;
using Xamarin.Forms;

namespace MyApp.Converters
{

public class ByteArrayToImageSourceConverter : IValueConverter
{ 
    public object Convert(object value, Type targetType, object parameter, CultureInfo culture)
    {
        if (value == null)
        {
            return null;
        }
        byte[] bytes = value as byte[];
        return ImageSource.FromStream(() => new MemoryStream(bytes));
    }
    public object ConvertBack(object value, Type targetType, object parameter, System.Globalization.CultureInfo culture)
    {
        throw new NotImplementedException();
    }
}

}

And in my XAML:

<?xml version="1.0" encoding="UTF-8"?>
<ContentPage xmlns="http://xamarin.com/schemas/2014/forms" 
                xmlns:x="http://schemas.microsoft.com/winfx/2009/xaml" 
                xmlns:converters="clr-namespace:MyApp.Converters; assembly=MyApp" 
                x:Class="MyApp.FriendsForm">
<ContentPage.Resources>
    <ResourceDictionary>
          <converters:ByteArrayToImageSourceConverter x:Key="bytesToImage"></converters:ByteArrayToImageSourceConverter>
    </ResourceDictionary>
  </ContentPage.Resources>
    <ContentPage.Content> 
        <ListView x:Name="listView">
            <ListView.ItemTemplate>
                <DataTemplate>
                    <ViewCell>
                ..............

Even before calling the function I get the above error when starting the app up. It seems related to the namespaces or xmlns but I just cant figure it out. Thank you for your help!
